The doorbell rang and Mrs Carson {#blank#}1{#/blank#} (open) the front door. Her heart sank when she saw Mrs Burbridge. Whenever Mrs Burbridge called, she stayed {#blank#}2{#/blank#} hours and hours.

    " Good afternoon, Mrs Carson," Mrs Burbridge said, " Do come in." Just as Mrs Carson had feared. Mrs Burbridge stayed for several {#blank#}3{#/blank#} (hour). It was nearly six o'clock and Mr Carson would be home {#blank#}4{#/blank#} work soon.

    Mrs Carson kept thinking about {#blank#}5{#/blank#} she would ask Mrs Burbridge to leave without {#blank#}6{#/blank#} (make) her angry. "Has your husband got home from work yet?" Mrs Carson asked. "Oh, yes," Mrs Burbidge answered, "he always {#blank#}7{#/blank#} (get) home at about five o'clock." "It's nearly six o'clock. Won't he be worried about you?" Mrs Carson said.

    "I thought of that," Mrs Burbridge said, "but it's so pleasant here. We've had such a {#blank#}8{#/blank#} (love) afternoon. You know what I'll do. I'll ring up my husband {#blank#}9{#/blank#} tell him to come round, too. May I use {#blank#}10{#/blank#} (you) phone, please?

    Each day in the United States, one person uses about 575 litres (公升) of water. In Japan, one person uses about 374 litres of water. {#blank#}1{#/blank#} in Kenya, one person uses only about 20 litres.

    Tomoyuki Tsutsui and Keitaro Kakoi are {#blank#}2{#/blank#} (Japan) university students. They raised money online to help people in Kenya. They wanted {#blank#}3{#/blank#} (they) to drink clean water. Tsutsui lives in Kisumu, Kenya. He lives in a house without running water, also {#blank#}4{#/blank#} (call) tap water. He knows {#blank#}5{#/blank#} difficult it is to live with little water. Most people cannot have water {#blank#}6{#/blank#} (easy) because there is no tap water in their houses. So, it's hard {#blank#}7{#/blank#} them to get water. They carry a tank (箱) of 20 litres three {#blank#}8{#/blank#} (time) a week. It is very heavy.

    Some residents (居民) can't go to northern Kisumu for water because it is too far. They must use rainwater or buy it from the shop.

    Tsutsui and Kakoi have a lot of money {#blank#}9{#/blank#} (solve) these problems now. {#blank#}10{#/blank#} company is laying a water pipe from northern Kisumu. When they finish the work, the residents of southern Kisumu will get water without travelling a long way.
